[FedCom] 400MHz bandpaln

[lists at lazygranch.com]

The Nevada Test Site did an exercise on one of those 400MHz pairs that was not on their trunking system. I wasn't there, but someone else sent me the info. (I'd have to dig up the frequency.) My point is it is a good plan to have those "special" frequencies handy. 

Regarding 380MHz, I put two system scans from Pro96com in the radio reference Nevada forum. An additional system recently showed up in Vegas. There have been the usual "key fob" issues. My two systems were heard around the range, not in Vegas.

Also in the RR Nevada forum, I listed contracts for a new tower at Creech with an antenna capable of 380-420MHz. The reason I'm pointing this out is another source of information is simply to troll www.fbo.gov and look for land mobile contracts. You can search for P-25, radio, etc. In fact, I found all the transmitter sites for the Edwards AFB trunk system that way. I posted that on the RR California forum.  The new Creech AFB tower will also hold a pager for the NTS. News to me, but apparently it already exists on the site and they are just moving it.  

You need to use RadioReference information with some caution. It is crowd sourced. Correct information is often "fixed" with incorrect information by well meaning (I hope) people that don't know what they are doing. I view RR as a starting point, but not an authority. I go to the actual fed references.

One thing to look for in the NTIA Red Book are the regional exceptions. The ground sensors at Groom Lake were on 151.5MHz. Clearly not for federal use. However, there is a footnote in the Red Book allowing the use at the NTTR on a non-interference basis.

A google search on interoperability will yield all sort of fed and state documents:

I don't have the link handy, but searching for FAA tower information often reveals federal transmitter tower sites. I found the Fallon ELMR sites locations that way.

Greg, at least domestically, the DoD 380 MHz band has a 10 MHz offset, with
380-390 being repeater 
outputs and 390-400 MHz repeater inputs. 

There are some exceptions to this, particularly with the Navy and their
shipboard trunked systems.

Simplex use has been seen throughout the 380-400 MHz range.

Does anyone have a list of users in the 380.00 to 399.99750 Mhz range, 
including which is input and output on repearters?
Thanks in advance.
Greg
